Answer: 
molecules are there in the flask
Explanation:
According to the ideal gas equation:
P = Pressure of the gas = 1 atm
V= Volume of the gas = 2.00 L
T= Temperature of the gas = 273 K 
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
1 mole of gaseous air contains = molecules
11.2 moles of gaseous air contains = 
molecules
gaseous molecules are contained in the flask.
C the South Pole gets 24 hours of daylight
Okay, so what you first do with this type of question is think about what a chemical change is. A chemical change is a change that can not be reversed. A physical change is something that can be reversed or done using temperature. e.x. Water freezing into ice is a physical change, where as combining vinegar and baking soda together releases a gas, which is chemical, or iron rusting in the presence of oxygen. Which one of these equations has one chemical molecule set that produces a different set?
